T0 of! whom [1 may (vi/warn llc it known that l, LEONHARD Lamnn'rir, asubject of Germany, and resident of Hobokcn. in the count of Hudson andState of New Jersey, have invented certain new and useful Improvementsin Demountable Vehicle Bodies, of which the following is aspecification.

This invention relates to vehicles in gen eral and in particular to thekind having removable bodies. I

The primary objects of mv invention are to provide a vehicle of simpleand inexpensivc construction with a removable and exchangeable body orbodies for the purpose of facilitating the loading, unloading and thetransportation of loaded and unloaded bodies from place to place whileusing but one power driven understructure, the chassis, and tofacilitate the manual individual mov ing of the body or bodies onfloorsor the ground upon. means specially adapted for this purpose andentirely independentof means for supporting the body .or bodies upon thechassis of the vehicle.

Other objects of my invention are to provide in combination with suchvehicle means for guiding the body within the chassis and means forfacilitating the unloadin and loading of the body from and. on the classis.

The more specific objects of my invention are to provide a chassis of avehicle with a frame for supporting the removable body and an unloadingframe for facilitating the gliding of the body down to the ground uponwheels pivotedly attached to the body and means for facilitating themoving of the bod down or up on the unloading frame and upon the chassisFrame.

The l orcgoing and still further objects will be readily observed fromthe lf'dlowing description and the arcornpai'iying drawings. in which:

Figure 11 is a detail sectional view illustrating the arrangement-of aside guideroller.

Figure 12 is a diagramlnatical view oi a vehicle chassis showing thebody frame in two positions, one when associated with the chassis, theother (in broken lines) when resting upon the unloadin frame.

Figure 13 is a detail view of the winding mechanism for facilitatingelevating or descending of the body in relation to the chassis.

Figure 14 illustrates a key for securing the body and unloading framesto the chassis.

In the drawings a chassis l of a motor driven vehicle is shown. the rearpart of which is preferably built out to a. rectangular frame. as seenin Figures 6, T and 8 or such frame may be readily attached to thestandard chassis. For convenience this frame will he called the chassisframe. It comprises an angle iron construction as shown, but may be alsomade of channels or other standard steel types. Its side bars 2 are heldtogether by a plurality of trans verse cross bars 3 upon which restrails 4- disposed longitudinally with the chassis. The ends of the railsin the rear arb somcwhat rounded oil as indicated at 5 for reasonsexplained later. Attachcd also to the cross bars 3 and extending overthe entire length of the side-bars 2. are angular guards 6 with aflaring upper edge 7.

Lodged within the outer leg of the sidebars 2 are anti-friction devices8, such as rollers or balls, upon which rollahly rest a generallyU-shapcd unloading frame 9 preferably made of two parallel channels andan angle connecting bar indicated at 10.

Attached also to the sidebars 2 is a plurality of guard brackets ll forkeeping the unlmidinf; frame i'rom idwaisclk' hiftiufl. At. the rear endof the side bars areend brackets 12 for engaging the downwardly rurvedand hoolclihc ends 1 f the unload inn frame. (See Figure 1'2.)

Any suitable body 14 may be fitted to rest upon the chassis frame byproviding it with (ill a body frame 15 preferably made of channel ironinto a rectangular shape and fitted with reinforcing cross bars 16. Atthe lower 1e of'the channels suitable lugs 17 are'provi ed as bearingsfor transversely disposed rollers 18 extending over the entire width ofthe body frame and adapted to rest and roll upon rails 4 of the chassisframe.

Rotatably lodged between the channel le of the body frame and disposedverti ca ly are guide rollers 19 extending somewhat beyond the bodyframe proper and adapted to engage the guards 6 of the chassis frame.These rollers and guards are provided for keeping the body in as nearlya central osition upon the chassis as possi le.

Attac ed at the bottom of the body are large rollers 20, rotatablymounted in yokes 21 which again may be rotated in horizontal directionbeing pivotally lodged at 22. These rollers are mounted-in pairs andsuspended above the unloading frame 9 without touching it when the bodyframe rollers 18 rest upon the rails of the chassis frame. They areguided by angle the upper surface 0 unloading frame 9, and facilitatetheir rollin Ithereupon when the body rollers leave t e rails 4. (See Fiure 12.)

n order to facilitate the moving of'the body onto or from the chassisaconventional winding mechanism indicated at 24- is pro vided belowthe'seat of the driver or at any other convenient place, and isconnected through cable ,25attached at one end to the drum 26 (Fi re 13)and at the other end by way of a ink 27 to hook 28 to the body 14. (SeeFigure 12.)

At both ends'of the body frame and corresponding therewith at thechassis frame are a rtures 29 and 30, respectively, throng which may bepassed a key 31 from either side of the vehicle for keeping the bodyfirmly united with the chassis when the vehicle travels. The keyconsistsbf a handle or ring 32 (Figure 14) a pin 33 and a springactuated lock bar whigh may be set at right angles after having p ssedthrough the respective frames.

Another lockin device is rovided at the end of the unloa mg frame orkeeping the latter in place when not in use. It consists of a pin 34 andhook 35 or any other convenient device for a. corresponding purpose.

Operation: When the body is to be 1owered from the chassis frame, theunloading frame is first released and lowered at one end to contact withthe floorin or ground. The upper or other end of the rame hooks againstbracket 12. The winding mechanism is then released and the body ispushed to the rear so that the wheels or rollers 20 come to rest uponthe unloading frame and i take off the weight of the body from rollersides 23 attached at 18 of the body frame. The'body is then rolled downuntil reaching the platform,- floor or ground where it may be movedmanua-lly or otherwise, while the rest of the vehicle may depart. y

In a similar way the loading of the bod is done. The unloading frame islowere the cable hooked to the body, wheels 20 are aligned with theframe guards 23 and the winding mechanism operated until the body ispulled into place.

It will be observed that the rails 4 are sloped and rounded at theirends at 5 to allow the rollers 18 to gradually take over the weight ofthe body from wheels 20.

Vhile the drawings show specific forms of my device, I reserve formyself the right to make changes and improvements to suit variousconditions.

Having described my invention, I claim:

1. In combination with a vehicle'comprising a chassis and a body, arectangular frame associated with the chassis and having a plurality ofcross bars, a plurality of parallel rails mounted upon the cross barsangular guards provided at both sides and extending over the wholelength .of the frame. anti-friction rollers associated with theextending outer leg of the lon framesides, two pairs of brackets attacheto the latter at both ends, :1 U-shaped frame adapted to roll upon saidrollers and having guiding means attached at its upper surface,mcans'for fastening said U-shaped frame to the first mentioned framewhen in inoperative position, a body under frame, a lurality oftransverse rollers rotatablyhel Within the body frame and adapted toroll u on said rails, vertically disposed guide rol are extendingsidewise beyond the body frame and adapted to engage said angular guardspivotably mounted rollers, attached in pairs to the body, extendingbelow the line of rollers ofuthe body frame and adapted to roll 'uponsaid U-shaped 'frame when the, body has left the chassis and upon the flor. when leaving said U-shaped frame, mean a or fasteningsaid body frameto said guar s when the b0 y rests upon the chassis and means forfacilitating the lowering of the body from the chassis and the rollingup of the body onto the chassis.
